Special Issue Information

Dear Colleagues,

With the escalating climate crisis and the accompanying biodiversity loss and agricultural productivity loss, plant health is attracting more attention from the research community. Wearable sensors that can minimally invasively monitor the health status of plants, for example, to detect biotic and abiotic stresses, are undergoing rapid growth in recent years. Many of the established know-hows in animal and human-targeted biosensors can be adapted for plant sensing. However, there are many issues that are specific to plants, such as the thick insulating cuticle, highly rough and complex surface topography, diverse organ shapes and anatomy, large species variability, harsh environmental conditions, etc.

This Special Issues aims to report up-to-date progress in wearable sensors for plant health monitoring. The sensing modality can be either physical or chemical, or a combination of both, such as hydration, sap flow, microenvironment (temperature and humidity), nutrient concentration, hormones, metabolites, etc. The sensors should have a form factor that is sufficiently small and lightweight for attachment on plants, either noninvasive or invasive. Progress in the miniaturization of readout electronics and wireless communication is also welcome. Demonstration of applications in either simulated or real-world scenarios should be considered in the areas of precision agriculture, crop breeding, biodiversity preservation, etc. In addition, perspectives on the development of this field, including relevant challenges, research directions, application prospects and associated challenges, are also welcome.

Plant wearable sensors have shown exceptional promise in continuously monitoring plant health. However, the potential adverse effects of these sensors on plant growth remain unclear. This study systematically quantifies wearable sensors’ interference with plant growth using two ornamental species, Peperomia tetraphylla and Epipremnum aureum. We evaluated the impacts of four common disturbances—mechanical pressure, hindrance of gas exchange, hindrance of light acquisition, and mechanical constraint—on leaf growth. Our results indicated that the combination of light hindrance and mechanical constraint demonstrated the most significant interference. When the sensor weight was no greater than 0.6 g and the coverage was no greater than 5% of the leaf area, these four disturbances resulted in slight impacts on leaf growth. Additionally, we fabricated a minimally interfering wearable sensor capable of measuring the air temperature of the microclimate of the plant while maintaining plant growth. This research provides valuable insights into optimizing plant wearable sensors, balancing functionality with minimal plant interference. Full article

To face the increasing requirement for grains as the global population continues to grow, improving both crop yield and quality has become essential. Plant health directly impacts crop quality and yield, making the development of plant health-monitoring technologies essential. Variable sensing technologies for outdoor/indoor farming based on different working principles have emerged as important tools for monitoring plants and their microclimates. These technologies can detect factors such as plant water content, volatile organic compounds (VOCs), and hormones released by plants, as well as environmental conditions like humidity, temperature, wind speed, and light intensity. To achieve comprehensive plant health monitoring for multidimensional assessment, multimodal sensors have been developed. Non-invasive monitoring approaches are also gaining attention, leveraging biocompatible and flexible sensors for plant monitoring without interference with its natural growth. Furthermore, wireless data transmission is crucial for real-time monitoring and efficient farm management. Reliable power supplies for these systems are vital to ensure continuous operation. By combining wearable sensors with intelligent data analysis and remote monitoring, modern agriculture can achieve refined management, resource optimization, and sustainable production, offering innovative solutions to global food security and environmental challenges.
